&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The solution by @ewatrrr is &nbsp;INCORRECT.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I came to bring a correct solution.



<pre>
 The conversion rule is 1 lbs = 16 oz.


 Of the total weigh of 2lbs 4oz, first pound is included into the @2.75 postage payment,

 so overweight is only 1lbs 4oz = 16+4 = 20oz.



 THEREFORE, the total postage cost is  2.75 + 20*0.35 = 9.75 dollars.


 She paid $20, so her change was $20 - $9.75 = $10.25.      <U>ANSWER</U>
